Ethiopian, Congolese, Columbian, Peruvian, Mexican, African, Thai, Guatemalan, Rwandan, and Indian.
I thought the selections were great and have never seen any of the above foods at the fair. I could do without the funnel cake, burger, and hotdog stands, but being able to have food from 10-12 countries in a few hours is pretty awesome.
The standouts for me were the doro wot (spicy Ethiopian chicken dish), the anticuchos (Peruvian beef heart skewers), and Choclo (Peruvian corn: yellowish-white, mildly sweet, and sport exceptionally large kernels).
